Cycle seat and clamp therefor

Abstract

A cycle seat clamp for selectively securing a cycle seat having a saddle and a truss to support posts having differing sizes is comprised of a first receptacle for receiving a support post of one size, a second receptacle connected to the first receptacle for receiving a support post of a second size, and a compression member for compressing one of the receptacles against a received support post to secure the cycle seat thereon. Also disclosed is a cycle seat comprising a clamp of the foregoing type.

What I claim is: 
     
       1. A cycle seat mountable on cycles having support posts of differing sizes, said cycle seat comprising: a saddle having an upper portion and a lower portion;   a truss attached to the lower portion of said saddle; and,   a clamp rotatably attached to said truss at a pivot point for mounting the seat on a cycle support post, said clamp comprising a plurality of receptacles for respectively receiving the support posts of differing sizes, wherein said receptacles are spaced generally equi-angularly about said pivot point.   
     
     
       2. A cycle seat according to claim 1 wherein said clamp further comprises means for compressing said receptacles against a received support post to clamp the cycle seat firmly on the post. 
     
     
       3. A cycle seat according to claim 2 wherein said receptacles comprise wall means defining first and second apertures of first and second sizes having parallel central axes, for selectively receiving support posts of corresponding first and second sizes. 
     
     
       4. A cycle seat according to claim 3 wherein said truss includes a pair of generally spaced side plates defining a central channel, and means for locating said clamp within said channel. 
     
     
       5. A cycle seat according to claim 4 wherein said side plates of said truss define a first set of bolt receiving apertures; and the axes of said first and second apertures of said clamp are generally parallel with the support post; and said clamp further includes wall means between said first and second apertures defining a second set of aligned bolt receiving apertures having coincident axes generally perpendicular to the axes of said first and second apertures; and said means for locating said clamp within said channel comprises a bolt extending through said first and second sets of bolt receiving apertures. 
     
     
       6. A cycle seat according to claim 5 wherein said bolt is threaded, and said means for compressing said receptacles against a received support post comprises a nut to be screwed on said bolt for compressing said clamp wall means against the received wall post. 
     
     
       7. A cycle seat clamp for selectively securing a cycle seat having a saddle and truss, to support posts having differing sizes, said clamp comprising: first receptacle means for receiving a support post of one size;   second receptacle means connected to said first receptacle means for receiving a support post of a second size; and,   compressing means for compressing said receptacle means against a received support post to secure the cycle seat on the support post, said compressing means further comprising pivot means attachable to a truss to rotatably vary the position of the receptacle means therewith; wherein said first and second receptacle means are spaced generally equi-angularly about said compressing means.     
     
     
       8. The clamp of claim 7 wherein said first and second receptacle means comprise resilient wall members defining first and second apertures configured for receiving support posts of the first and second sizes, respectively. 
     
     
       9. The clamp of claim 8 wherein said first and second apertures have substantially parallel axes. 
     
     
       10. The clamp of claim 7 wherein said mounting means includes stepwise rotatable mounting means. 
     
     
       11. The clamp of claim 9 wherein: each of said receptacles comprises an arcuate end wall; and,   said clamp further includes connecting means having side walls comprising continuous extensions of said arcuate end walls.   
     
     
       12. The clamp of claim 11 wherein said connecting means further comprises inwardly turned lips extending generally perpendicularly from said side walls intermediate said first and second apertures, said lips having first and second arcuate end edges with configurations corresponding to configurations of said first and second apertures. 
     
     
       13. The clamp of claim 12 wherein the cycle seat truss comprises opposing side plates defining a channel and said clamp is rotatably secured within the channel. 
     
     
       14. The clamp of claim 13, further comprising: first set of serrations on the outer faces of each of said side walls; and,   a second set of serrations on said clamp configured for mating engagement with said first set;   said clamp being rotatable within said channel in a stepwise manner.   
     
     
       15. The clamp of claim 14 further comprising mounting apertures in each of said side walls and said side plates, said mounting apertures being in registration for receiving axle means for rotatably supporting said seat. 
     
     
       16. The clamp of claim 14 wherein said clamp further comprises a pair of mounting inserts each disposed intermediate said side walls and said side plates, said second set of serrations being formed on said pair of mounting inserts. 
     
     
       17. The clamp of claim 16 wherein said clamp further includes axle means for rotatably supporting said seat, and said mounting inserts each comprising: a member bearing said serrations on one side thereof;   a central aperture for receiving said axle means; and,   outwardly turned lips for engaging edges of said side plates to maintain said inserts in place relative to said side plates.   
     
     
       18. The clamp of claim 17 wherein said axle means comprises a threaded bolt and cooperating threaded nut. 
     
     
       19. The cycle seat of claim 8 wherein the internal diameter of said first aperture is about 5/8" and the internal diameter of said second aperture is about 7/8".
